Black-veined White crataegi Egg Batch

Egg batches (at least 30 eggs) will be available in May/June. The larvae do well sleeved on Hawthorn (their preferred foodplant), Plum, Blackthorn, Plum or Apple. They live gregariously, spinning a very small and concealed web on the branch, in which they hibernate. Leave the sleeve untouched for the winter. In spring they awake as soon as the buds burst, and begin to grow very quickly. They pupate often collectively, making very brightly coloured, angular pupae which are greenish white, with contrasting markings in black and yellow.
